Question

1. In a certain flower, the color red (C) is dominant over the color white (c) and the presence of thorns (T) is dominant over the absence of thorns (t). The null hypothesis is that there is no difference in the observed distribution of flowers from what is expected of a dihybrid cross. State the alternative hypothesis.
a. The observed distribution of recessive traits is less than what is expected of a dihybrid cross.
b. The observed distribution of homozygotes exceeds what is expected of a dihybrid cross.

Answer 1

c. The observed distribution of heterozygotes exceeds what is expected of a dihybrid cross.
d.The observed distribution of flowers differs from what is expected of a dihybrid cross.
